BackgroundImmune Checkpoint Inhibitors (ICI) have been progressively used in cancer treatment and produced unique toxicity profiles. This systematic review aims to comprehend the patterns and occurrence of treatment-related adverse events (trAEs) based on ICI.MethodsPICOS/PRISMA methods were used to identify published English-language on PubMed, Web of Science, and Scopus from 2015 to 2020. Published clinical trials on ICI monotherapy, combined ICIs, and ICI plus other treatment with tabulated data on grade≥3 trAEs were included. Odds ratio (OR), χ2 tests were used to analyze for effect size and associations.ResultsThis review included 145 clinical trials involving 21786 patients. Grade 3-5 trAEs were more common with ICI when they were plused with other treatments compared with ICI monotherapy(54.3% versus 17.7%, 46.1%, p<0.05). Grade 3-5 trAEs were also more common with CTLA-4 mAbs compared with anti-PD-1 and anti-PD-L1 (34.2% versus 15.1%, 13.6%, p<0.05). Hyperthyroidism (OR 3.8, 95%CI 1.7–8.6), nausea (OR 3.7, 95%CI 2.5–5.3), diarrhea (OR 2.7, 95%CI 2.2–3.2), colitis (OR 3.4, 95%CI 2.7–4.3), ALT increase (OR 4.9, 95%CI 3.9–6.1), AST increase (OR 3.8, 95%CI 3.0–4.9), pruritus (OR 2.4, 95%CI 1.5–3.9), rash (OR 2.8, 95%CI 2.1–3.8), fatigue (OR 2.8, 95%CI 2.2–3.7), decreased appetite (OR 2.4, 95%CI 1.5–3.8), and hypophysitis (OR 2.0, 95%CI 1.2–3.3) were more frequent with combined ICIs. Diarrhea (OR 8.1, 95%CI 6.4–10.3), colitis (OR 12.2, 95%CI 8.7–17.1), ALT increase (OR 5.1, 95%CI 3.5–7.4), AST increase (OR 4.2, 95%CI 2.8–6.3), pruritus (OR 4.1, 95%CI 2.0–8.4), rash (OR 4.4, 95%CI 2.9–6.8), hypophysitis (OR 12.1, 95%CI 6.3–23.4) were more common with CTLA-4 mAbs; whereas pneumonitis (OR 4.7, 95% CI 2.1–10.3) were more frequent with PD-1 mAbs.ConclusionsDifferent immune checkpoint inhibitors are associated with different treatment-related adverse events profiles. A comprehensive data in this systematic review will provide comprehensive information for clinicians.

Patients with extensive-stage small cell lung cancer (ED-SCLC) have a very short survival time even if they receive standard cytotoxic chemotherapy with etoposide and platinum (EP). Several randomized controlled trials have shown that patients with ED-SCLC who received a combination of EP plus immune checkpoint inhibitors (ICIs) had superior survival compared with those who received EP alone. We conducted a systematic review and network meta-analysis to provide a ranking of ICIs for our primary endpoints in terms of overall survival (OS), progression free survival (PFS), and objective response rate (ORR), as well as our secondary endpoint in terms of adverse events. The fractional polynomial model was used to evaluate the adjusted hazard ratios for the survival indicators (OS and PFS). Treatment rank was estimated using the surface under the cumulative ranking curve (SUCRA), as well as the probability of being best (Prbest) reference. EP plus nivolumab, atezolizumab or durvalumab had significant benefits compared with EP alone in terms of OS (Hazard Ratio HR = 0.67, 95% Confidence Interval CI = 0.46–0.98 for nivolumab, HR = 0.70, 95% CI = 0.54–0.91 for atezolizumab, HR = 0.73, 95% CI = 0.59–0.90 for durvalumab) but no significant differences were observed for pembrolizumab or ipilimumab. The probability of nivolumab being ranked first among all treatment arms was highest (SCURA = 78.7%, Prbest = 46.7%). All EP plus ICI combinations had a longer PFS compared with EP alone (HR = 0.65, 95% CI = 0.46–0.92 for nivolumab, HR = 0.77, 95% CI = 0.61–0.96 for atezolizumab, HR = 0.78, 95% CI = 0.65–0.94 for durvalumab, HR = 0.75, 95% CI = 0.61–0.92 for pembrolizumab), and nivolumab was ranked first in terms of PFS (SCURA = 85.0%, Prbest = 66.8%). In addition, nivolumab had the highest probability of grade 3–4 adverse events (SUCRA = 84.8%) in our study. We found that nivolumab had the best PFS and OS in all combinations of ICIs and EP, but nivolumab also had the highest probability of grade 3–4 adverse events in our network meta-analysis. Further head-to head large-scale phase III randomized controlled studies are needed to verify our conclusions.

e15110 Background: Immune checkpoint inhibitors (ICIs) yield remarkable clinical efficacy in the treatment of cancer. With the increasing use of ICI therapies, the dissemination of immune-related adverse events (irAEs) data is essential. This study aimed to investigate the pattern of onset and resolution of ICI-induced irAEs in cancer. Methods: Phase II–III clinical trials with single or multiple arms studying ICI-based treatments in cancer published between January 2007 and December 2019 were included. The pooled median time to onset (PMT-O), resolution (PMT-R), and immune-modulation resolution (PMT-IMR) of irAEs were analyzed based on irAE categories and severity grades using the metamedian package of the R software. Subgroup analyses were performed based on different ICI drugs, ICI doses, and cancer types. Results: Twenty-two eligible studies involving 23 clinical trials and 8,436 patients were included. On average, irAEs occurred at 6.1 weeks (95% confidence interval [95% CI], 5.7–7.4) after the initial ICI-based treatment. The first four irAEs with the shortest PMT-O were hypersensitivity/infusion reaction (3.1 weeks), neurological (4.0 weeks), skin (4.1 weeks), and gastrointestinal (6.1 weeks) events. IrAEs were resolved within 4.5 weeks (95% CI, 4.0–6.1), with the shortest and longest PMT-R for hypersensitivity/infusion reaction (0.1 weeks) and endocrine events (28.7 weeks), respectively. The application of immune-modulation drugs prolonged the general resolution time to 5.9 weeks, with the shortest and longest PMT-IMR for hypersensitivity/infusion reaction (0.2 weeks) and endocrine events (56.6 weeks), respectively. Grade ≥ 3 irAEs showed a significantly longer PMT-O (7.9 vs. 6.1 weeks; P < 0.01) compared with all grade irAEs. Nivolumab + ipilimumab had a significantly shorter PMT-O than nivolumab alone (6.0 vs. 8.2 weeks; P < 0.01). A significantly shorter PMT-O was observed for lung cancer compared with that for melanoma (4.7 vs. 6.1 weeks; P = 0.02). Conclusions: This study revealed the pattern and kinetics of the time to onset and resolution of irAEs in pan-cancers, which will promote the comprehensive understanding, timely detection, and effective management of ICI-induced irAEs.

e17030 Background: Prostate cancer is one of the leading cancers in men with an estimated 191,930 new cases in 2020 in the USA alone. Treatment options for metastatic castration resistant prostate cancer (mCRPC) have evolved in recent years. Immunotherapy involving vaccines like sipuleucel-T, PROSTVAC and immune checkpoint inhibitors have been evaluated in these patients. We present a systematic review and meta-analysis of the randomized controlled trials (RCTs) testing the effect of immunotherapy in mCRPC. Methods: A systematic search was performed using PubMed, Embase and the Cochrane library without language limitations from inception to January 3, 2021. The primary outcome was overall survival (OS) and secondary outcomes were progression free survival (PFS), prostate specific antigen (PSA) reduction ≥ 50% and incidence of grade 3-4 adverse events. The analysis of OS, PFS was done using random effects hazard ratio (HR) by generic inverse variance method and analysis of PSA reduction ≥ 50% and grade 3-4 adverse events was done using random effects risk ratio (RR) by the Mantel-Haenszel method. Results: 12 RCTs comprising 4109 patients were included in the analysis. There was a statistically significant improvement in OS (HR 0.89; 95% CI (0.81, 0.97)) and PFS (HR 0.83; 95% CI (0.76, 0.92)) in the immunotherapy arm compared to placebo or standard treatment arms with moderate quality of evidence. Patients in the immunotherapy group had significant reduction in PSA ≥ 50% (RR 1.71; 95% CI (1.09, 2.68)) but also had statistically significant increased risk of grade 3-4 adverse events (RR (1.25; 95% CI (1.02, 1.54)) when compared to placebo and the standard treatment group. Subgroup analysis showed that the use of vaccine therapy in prostate cancer leads to significant improvement in OS (HR 0.83; 95% CI (0.74, 0.93)) and PFS (HR 0.80; 95% CI (0.67, 0.95)) compared to placebo and standard treatment. The use of immune checkpoint inhibitors was not associated with statistically significant improvement in OS (HR 0.98; 95% CI (0.88, 1.09)) but is associated with improvement in PFS (HR 0.87; 95%CI (0.81, 0.94)). Conclusions: This meta-analysis showed that immunotherapy led to significant improvement in OS, PFS and PSA reduction of ≥ 50%. However, there is an increased incidence of grade 3-4 adverse events with the use of immunotherapy when compared to other standard therapies and placebo. The improvement in overall survival is limited to the use of vaccine therapy and not to immune checkpoint inhibitors. Careful use of selective forms of immunotherapy in mCRPC can lead to greater improvement in survival.

BackgroundImmune checkpoint inhibitors (ICIs) have dramatically altered the treatment landscape for patients with melanoma. However, their use also generates unique immune-related adverse effects (irAEs). We performed a systematic review and network meta‐analysis to compare the risk of pneumonitis associated with ICIs for patients with advanced or metastatic melanoma.MethodsPhase II/III randomized clinical trials (RCTs) with ICIs were identified through comprehensive searches of multiple databases. An NMA was conducted to compare the risk of pneumonitis associated with ICIs and all‐grade (grade 1‐5) and high‐grade (grade 3‐5) immune‐related pneumonitis (IRP) were estimated by odds ratios (ORs).ResultsA total of 10 randomized clinical trials involving 5,335 patients were enrolled in this study. Conventional chemotherapy was associated with a lower risk of grade 1–5 IRP compared with ICIs monotherapy (OR, 0.14, 95% CI, 0.03 to 0.73) and dual ICIs combination (OR, 0.03, 95% CI, 0.00 to 0.19). In addition, dual ICIs combination showed a noticeably higher risk than ICI monotherapy (OR, 4.45, 95% CI, 2.14 to 9.25) of grade 1–5 IRP. No significant difference in grade 1–5 IRP was observed between cytotoxic T lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1) inhibitors. As to grade 3‐5 IRP, no statistically significant difference was found among different ICIs-based regimens.ConclusionThese findings revealed that ICIs could increase the risk of all-grade pneumonitis for patients with advanced melanoma, compared with conventional chemotherapy. Dual ICIs combination could further increase the risk of all-grade pneumonitis than ICIs monotherapy. There was no significant difference in the risk of pneumonia between CTLA-4 and PD-1 inhibitors.

Immunotherapy has become a standard of care in oncology, following the recent approvals of cytotoxic T-lymphocyte-associated protein-4 and programmed cell death-1 inhibitors in lung cancer, melanoma, renal cell carcinoma, Hodgkin's lymphoma, bladder, head and neck cancers. Besides their efficacy, these agents also generate specific immune-related adverse events. Due to the increasing prescription of immune-checkpoint inhibitors, the incidence of immune toxicity will continue to rise. The awareness of immune-related adverse events is key to ensuring both diagnosis and management of the possible serious adverse events. Although severe immune-related adverse events remain rare, they can lead to discontinued treatment or to death if they are not forecasted and managed properly. Even if lung toxicity is not the most frequent adverse event, it remains critical as it can be life-threatening. Herein, the main aspects of pulmonary toxicity are reviewed and guidelines are also proposed in order to manage the possible side-effects.

Introduction: With the widespread use of immune checkpoint inhibitors (ICIs), we are facing challenges in the management of immune-related adverse events (irAEs). We aimed to characterize the spectrum of toxicity, management, and outcomes for irAEs. Methods: Patients who were treated with at least one ICI in clinical trials, expanded access programs, or routine clinical practice were included. Clinical and laboratory parameters were collected retrospectively to determine the incidence of irAEs, methods of management, and treatment outcomes. Results: A total of 255 patients were screened retrospectively. Of these, 71 (27.8%) patients developed irAEs. More than 2 different types of irAEs were detected in 16 (6.2%) out of 255 patients. A total of 3177 doses were given to 255 patients. In 93 (2.9%) of the 3177 doses, 1 episode of irAEs was experienced. A total of 22 out of 93 (23.7%) episodes were reported as grade 1, 49 (52.7%) as grade 2, 19 (20.4%) as grade 3, and 3 (3.2%) as grade 4. The most frequently seen irAEs were pneumonitis, hepatitis, and hypothyroidism. With regard to treatment, 39 out of 93 episodes (42%) of any grade irAEs occurred after anti–programmed cell death-1 therapy, 47 (50.5%) occurred following administration of anti–programmed death-ligand 1, and 7 (7.5%) occurred after combination treatments. Conclusion: With the increased use of immunotherapeutic agents, increased awareness and early recognition are required for effective management of irAEs. Our experience as a single institution might be of use for health care providers in oncology.

Background: This network meta-analysis assessed the comparative risk of grade 3–5 and grade 5 treatment-related adverse events (TRAEs) for immune checkpoint inhibitors (ICIs), either alone or in combination with other modalities, for cancer treatment. Methods: PubMed, Embase, Cochrane Library, Web of Science, and recent predominant oncology congresses were searched for relevant phase II and phase III randomized controlled trials (RCTs). As outcomes, grade 3–5, and grade 5 TRAE outcomes were reported as odds ratios and 95% confidence intervals. Results: In 67 RCTs involving 36,422 patients and 19 ICIs, the incidence of grade 3–5 and grade 5 TRAEs was 17.9% and 0.8% with ICI monotherapy and 46.3% and 1.4%, respectively, with combinatorial therapy. Pneumonitis was the most common cause of grade 5 TRAEs following either monotherapy (16.3%) or combinatorial therapy (11.4%). Regarding grade 3–5 TRAEs, atezolizumab + chemotherapy (CT) and antiangiogenic therapy (AT) (atezolizumab + CAT), pembrolizumab + CT, ipilimumab + CT, and atezolizumab + CT were more toxic than any ICI monotherapy, pembrolizumab or nivolumab + radiotherapy (RT), and ICIs dual therapy (durvalumab + tremelimumab and nivolumab + ipilimumab). Tremelimumab, ipilimumab, durvalumab, and pembrolizumab were, however, associated with higher grade 5 TRAEs than combinatorial treatments. Atezolizumab + CAT was the most toxic and nivolumab + RT was the least toxic of combinatorial treatments; among monotherapies, tremelimumab and avelumab were the most and least toxic, respectively. The toxicity ranking changed with type of grade 3–5 TRAEs. Conclusions: Compared with combinatorial therapy, ICI monotherapy caused lower grade 3–5 TRAEs, but some monotherapies resulted in a higher incidence of fatal TRAEs. Atezolizumab + CAT and nivolumab + RT were the most and least toxic of combinatorial treatments, respectively, and tremelimumab and avelumab were the most and least toxic of the monotherapies, respectively.
